Heating and Drying Ovens

Cooled Vacuum Oven VOcool


Product Description

Take a closer look at the VOcool cooled vacuum oven, for the gentle drying of bacteria and starter cultures. Freeze-drying, the most common means of drying starter cultures and probiotics is very energy-intensive. Furthermore, some bacterial strains do not survive the freezing process. Thanks to low-temperature vacuum drying, unstable substances can be dried in the VOcool at moderate temperatures above zero without causing too much damage to the cell structure. Even more, program-controlled storage and transport scenarios for determining the behavior of active ingredients or volumes at different pressure and temperature conditions can be simulated.

Featuring a MEMory CardXL, you’ll have confidence in process safety with a temperature profile file where up to 40 ramps can be stored and re-used as often as you want. Celsius software enables convenient and extensive programming and documentation of processes.

Memmert is one of the leading manufacturers of temperature controlled appliances for your laboratory. Made in Germany, these units are 100% AtmoSAFE meaning not only are you purchasing a superior product technologically, but also one that was made considering the environment.

Whether you’re looking for small (32 liters) or large (1060 liters) volume chambers, working with standard applications or requiring a high demand for functionality, programming or documentation - Memmert have you covered. STEQ America is proud to offer Memmert’s range of heating and drying ovens which feature user-friendliness and state-of-the-art communication interfaces as a standard. Each appliance is tested according to the strict requirements of DIN 12 880: 2007-05 and is equipped with maximum security capabilities to keep you, the operator, safe at all times.

Beautiful and functional, Memmert’s stainless steel is scratch resistant, hygienic, robust and ever-lasting.

Applications for heating & drying ovens include:
• Sample storage
• Water content

Peltier technology for energy savings

The compact, energy-saving and extremely accurate Peltier cooling technology ensures a surface temperature distribution with a maximum deviation of ±1 K across the entire temperature range. Memmert is the only manufacturer worldwide offering digital pressure control as a standard for their vacuum ovens. Ramp programming of temperature and vacuum (-cycles) in combination with direct heating of shelves allows for turbo processes and no residual moisture.
